Material Examined 



These shells show almost invariably but three teeth- the parietal, 

 columellar, and lower palatal, with the upper palatal represented if at all 

 only by a very small tooth or a mere trace. No angular lamella was noted 

 in the case of any of the specimens cleaned, in this particular differing from 

 the race of V. modesta found in Glacier National park, Montana, which 

 are mainly of the parietalis type (Berry, 1919, p. 204). Similarly toothed 

 shells from the two lots are quite closely alike, however. The same speci- 

 mens seem already to have been recorded in print by Whiteaves (1905, 

 p. 171).
